Silicon carbide (SiC) particle can be bonded together by being sintered, to form stone ceramic comprising High melting temperature and high thermal conductivity coefficient, so that this based article is ideal for high temperature application.A kind of such application is to can be used for Spread the heat-conducting plate of heating.For example, in technology for making glass, SiC plate can be efficiently used for generating from smaller heat source Heat diffusion is gone out, so as to more uniformly propagate heat in predeterminated target.Therefore, it may be deposited in technology for making glass In such SiC plate, it is placed in melten glass (or container containing melten glass) and is configured to the heat of heating melting glass or container Between source.For example, the fire resisting formed body that can will be configured to molten glass into glassware is placed in SiC structure, add Thermal element is placed in outside SiC structure.Then, the thermal energy that SiC structure can be used to grow up heating element is transmitted to forming Body.

Another material for being usually used in glass manufacture is platinum (Pt).The high melting temperature and corrosion resistance of platinum are for usually opening up It is particularly useful for revealing the manufacture of the optical quality glass of high melting temperature.For example, in some technology for making glass, such as In fusion down draw process described below, many containers and pipeline for being used for transmission and adjusting melten glass are by platinum or platinum alloy (for example, platinum-rhodium alloy) is formed.

Therefore, it (is especially used to produce those of high melting temperature glass technique in the production of glassware when discovery In) it is common at a high temperature of, when to be widely used in both materials of glass manufacture be incompatible, this is unfortunate.Such temperature is logical Often more than 1000 DEG C.At high temperature, for example, greater than about 900 DEG C of temperature, silicon carbide and platinum react to form low melting temperature silication Platinum reaction product, such as Pt₂Si.In temperature to of about 1100 DEG C, it is possible to create PtSi, Pt₂Si、Pt₂Si₅And Pt₃One in Si Kind is a variety of.In addition, the kinetics of Pt-SiC interaction is more positive in the platinum side side ratio SiC for interaction.Cause This also results in the burn through of platiniferous component even the contact between the component containing SiC of short time period and component containing Pt.When containing When platinum component is intended to accommodate the component of melten glass, burn through can have catastrophic results.For example, impaired containing melten glass Container will lead to the loss and/or product loss of production time, and in the case where catastrophic burn through, will cause apparent people Member's harm.

As described below, the formed body for certain technology for making glass (for example, fused glass manufacturing process) usually fills It is contained in the outer cover (for example, Muffle furnace) formed by SiC plate.Heating element (for example, stratie) can be placed in outer cover Outside simultaneously generates thermal environment appropriate in outer cover (for example, in the space that outer cover limits), and/or maintains in formed body or shape The suitable forming temperature (viscosity) of melten glass on body.In order to ensure the abundant heating of formed body and melten glass, outer cover Wall is usually formed by silicon carbide.Although formed body itself is formed by refractory material (for example, aluminium oxide or zirconium oxide), at Body includes the platiniferous end cap for being placed in the opposed end of formed body, for guiding the melten glass stream on formed body and preventing from melting Glass is revealed from formed body end, otherwise this may upset manufacturing process in the case where no end cap.

In general, providing enough spaces, between silicon carbide wall and platinum end cap to prevent the contact between them.But The variation of manufacturing process, which may cause, needs bigger formed body.In practice, using existing device, including outer cover.Therefore, exist Under some cases, when being replaced with larger formed body, for first between the platinum end cap and silicon carbide wall of a kind of formed body Beginning gap may reduce.Further, since the high cost of platinum, the platinized platinum thickness for producing end cap is as small as possible.Therefore, melten glass Can platinum be heaved in the Fluid pressure that formed body end (for example, distal end) generates, or even more so that platinum end cap with far from Body and mobile towards the direction of enclosure wall.Finally, the thermal expansion of formed body is it is also possible that obtain between platinum end cap and enclosure wall Gap turn narrow.What the arrival end of formed body was usually fixed.Therefore, either as the result of initial heating or as glass The result (for example, being changing into more high melting temperature glass) of variation is formed, the expansion of formed body can generate (for example, formed body Longitudinal direction) variation of the large scale of formed body, equally reduce enclosure wall (for example, side wall and/or end wall) and end cap it Between gap.The influence of aforementioned device variation, thermal expansion and end cap deformation can individually or mode in any combination leads to outer cover Silicon carbide-containing wall and end cap between unintentional contact and the subsequent failure of end cap (sometimes within a couple of days of contact).This Text equipment described below is configured to prevent the contact between platinum end cap and outer cover.
